Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468636, here are decompositions:

  • 37 + 2147468599 = 2147468636
  • 73 + 2147468563 = 2147468636
  • 139 + 2147468497 = 2147468636
  • 193 + 2147468443 = 2147468636
  • 367 + 2147468269 = 2147468636
  • 463 + 2147468173 = 2147468636
  • 673 + 2147467963 = 2147468636
  • 823 + 2147467813 = 2147468636

Showing the first eight; more decompositions exist.
